I do not want audible traffic and detectable devices put on every intersection
where there is a traffic signal. I am blind traveler with a white cane. I have
lived in Oregon, Washington, Idaho, and Utah. With the correct training I have
been able to navigate all different types of intersections in good and bad
weather conditions. Audible traffic signals can make it difficult to listen to
traffic and make it safe for me to cross streets. It will increase the sound
problems in cities where there is alot of signals close together. The problem is
you can hear the sounds from the audible signals from other intersections and it
can be confusing to blind persons. We can use the money that it will cost for
better rehabilitation services, education, and to find better employment. When i
lived in Salt Lake City, Utah they have audible traffic signals in the downtown
area. They were making so much noise that people complained to the city to have
them shut off at night time. The other problem that it allows the blind to rely
on audible traffic signals and not the traffic and can be a safety danger. I do
agree with the National Federation of the Blind views on this issue. Most
intersections do not require an ATS for the accessibility and safety of blind
pedestrians. Only those intersections with complex geometry, complex
signalization, or varied signalization for each lane may be appropriate for an
ATS.
- Vibrotactile indicators should be used in preference to audible signals in
order to minimize noise distractions and better promote safety. Locator tones
should not be included in the final guidelines and may be subject to further
research.
- Detectable warnings: At most intersections the built environment provides
ample accessible cues to determine the difference between the sidewalk and the
street. A slope of less than 1:15 in crossing from the sidewalk to the street
(including medians and islands) may not be detectable and should be identified
with a detectable warning.
These limited locations should be checked out by city transportation
personnel and competent blind persons. The Vibrotactile indicators is more
useful to blind and elderly persons who also may have hearing difficulties.
Thank you for your consideration to my comments on this issue.
Sincerely yours,
Jerry Hathaway
